' ADVERTISING siGN.

To all whom it may concern:

Be it known that I, PETER LA GRAssA, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Advertising Signs; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has reference to signs carried under the sup-porting planes of aircraft, the object being to provide a simple and inexpensive, yet an efficient and reliable means for connecting a sign with a supporting wing, without weakening the latter in any appreciable sense.

lVith the foregoing in view, the invention resides in the novel subject matter herein after described and claimed, the description being supplemented by the accompanying drawing.

Figure 1 is a sectional view through a supporting plane showing the association of the invention therewith.

Figure 2 is a fragmentary plan view.

Figure 3 is a sectional view as indicated by line 3-3 of Fig. 1.

I have shown in the accompanying drawing, a supporting plane 1 which may be con sidered as the. plane of a monoplane or as the lower plane of a biplane, said plane including the usual main struts 2 and the front and rear tip-rails 3 and 4 along the front and rear edges of the plane. Below the plane 1, a sign is provided which preferably consists of separate illuminated letters such as those indicated by the numeral 5. These letters have been shown adjustably and removably connected at 6, with a pair of parallel, horizontal bars 7 disposed under the tip-rails 3 and 4, and similarly connected at 6 with additional bars 7 positioned under the main spars 2. The last named bars 7 a have been shown connected with the spars 2 by vertical hangers 8, the connections between said hangers and spars being preferably established in the manner shown.

Secured at their lower ends to the bars 7, I have shown front and rear hangers 9 adapted to extend vertically across the front and rear edges of the plane 1, each of said hangers being provided with vertically spaced inwardly extending arms 10 to strad- Application filed March 11, 1924. Serial no. 698,516."

dle said front and rear edges, bolts or the like 11 being passed through said arms and the rails 3 and 4, to secure the hangers 9 1n place.

Before applying the hangers 9, the front and rear edges of the plane 1 are by preferwithin the scope of the invention as claimed,

minor changes may be made.

Attention is directed to the fact, that as the letters 5 are of light sheet metal, they have a tendency to vertically vibrate at their ends, beyond the hangers 8, but upward thrusts are resisted by the lower arms 10 of the hangers 9, and downward thrusts are similarly resisted by the upper arms 10. Thus, excessive vertical vibration of the ends of the letters, about the bars 7* as fulcrums, is effectively prevented.

I claim:

1. The combination with an aircraft having a supporting plane, of a sign under said plane, and supporting means for said sign including plane-carried hangers spaced inwardly from the front and rear edges of the plane, and other hangers having vertically spaced arms embracing said front and'rear edges of the plane and secured thereto 2. The combination with an aircraft having a supporting plane, of channel-shaped metal bindings along the front and rear edges of said plane,'a sign under said plane, and supporting means for said sign including hangers having vertically spaced. arms respectively overlying and underlying the aforesaid bindings, and fasteners passing through said arms, bindings, and the edge portions of the plane.

3. An attachment for a plane-supported aircraft comprising a sign for dispositionunder a supporting plane of the craft,and sign-supporting means including hangers for attachment to the plane in inwardly spaced relation, with the front and rear edges of the latter, and additional vertical hangers outwardly spaced from the first named hangers and having vertically spaced rear edges of the plane, and channel-shaped i0 arms adapted to embrace and to be secured metal bindings adapted. for application to to the front and rear edges of the plane. said edges of the plane, the aforesaid arms 4. An attachment for a plane-supported being adapted to respectively overlie and 5 aircraft comprising a sign for dis-position underlie said bindings.

under a supporting plane of the craft, sign- In testimony whereof I have hereunto af- 15 supporting means including vertical hangers fixed my signature.

having Vertically spaced arms adapted to embrace and to be secured to the front and PETER LA GRASSA.
